After two seasons of tracking Rusty (Graham Patrick Martin) through the emotional turmoil he felt after being abandoned by his family and forced to prostitute himself to survive, the TNT drama’s third season (premiering Monday, June 9 at 9/8c) will finally introduce Sharon Beck, the mother who eventually left him behind. Eureka and 24 alum Ever Carradine will play the crucial role, Major Crimes creator James Duff tells TVGuide.com.
